Specification of Letters Patent.

Application filed September 17, 1909. Serial No. 518,258.

This invention relates to a power controllet for machinery and particularly to a mechanism controlled in the movement of the cover of a centrifugal extractor or other machine for shifting the driving means therefor.

The invention has for an object to provide a novel and improved construction between a movable cover member and power controlling mechanism for a machine and comprises-a bell-crank lever mounted uponthe machine and connected with the cover by a pivoted link and also having a connecting rod extending to an actuating lever by which the power controlling mechanism is operated.

Another object of the invention is to proivide an improved connection between the movable cover of a machine and an overhead driving shaft and comprises oppositely disposed crank levers connected together by a rod, one thereof having a link connection a link connection with a power shifting device. 2

Other and further objects and advantages of the invention will be hereinafter set forth and the novel features thereof defined by the ap ended claims.

n the drawings-I igure 1 is an elevation showing the application of the invention to an extractor; Fig.- 2 a detail vertical section showing the connecting mechanism in Fig. 3 is a detail front elevation of the mounting for the actuating lever; Fig. 4 is a detail rear elevation of the bellcrank lever and connection therefrom; Fig. 5 is a detail top plan; Fig. 6 is a detail of the shifter lever Fig. 7 is a top plan View of a modified form of the invention, and Fig. 8 is a side elevation thereof.

Like numerals of reference refer to like parts in the several figures of the drawings. The numeral 10 indicates the casin of a centrifugal extractor of any desired conhad therein to the accompanying drawstruction, the revolving member of which is driven by the shaft 11 provided with a pulley 12 as indicated in Fig. 1. This casing is provided with a cover 13 pivotally mounted upon the top thereof at 14:. The casing is also provided with a rear guard Wall 15 having an opening or aperture 10 through which a connecting'link 17 extends. This link is pivotally connected to the cover by means of lugs 18 and is at its opposite end 19 pivoted to a crank lever 20 which may comprise a bell-crank as shown or any other form having arms disposed at an angle to each other. While the invention is particularly applicable to an extractor cover, which has been shown for the purpose of illustration, still it may beapplied to a movable part of any other character of machine.

The crank lever 20 may comprise the elongated hub 21 pivotally mounted between ears 22 extended from an attaching plate 23, these parts forming a supporting bracket therefor. The arm 24 of the lever is formed with a bifurcated end 25 to receive the end 19 of the link 17 While the oppositely disposed arm 26 of the lever is adapted to reeeive a socket 28 having pivoting cars 27. This socket receives the lower end of the connecting member which is here shown as adjustable and comprises the tube or rod 29 secured in the socket and provided at its upper end with an apertured block 30 adapted to be adjusted in. position thereon by means of the set screw 31. receives the upper member 32 of the connecting rod which is also adj nstably secured by the set screw 33 as shown in Fig. 4. The upper end of the connector 32 is secured within the socket 234 which is provided with an elongated hub 35 disposed between and pivoted to the bifurcated arms 36 of the shifter lever 37. This lever is provided with an arm 38 disposed at an angle to the arm 36 thereof and provided with a bifurcatcdfrce end 39 between which the shifter link 40 is pivotod'at 4 As showing a desirable means for mounting the shifting lever 37 which comprises the This block also actuating member for the power controlling means, we have illustrated in Figs. 2 and 3".

a clamp having an enlarged bearing l3 disposed between thearms 30 of the lever 37 and pivoted thereto. .This clamp is provided with a set screw 44. by which it may be movement relative to said collar clamped in position upon any desired support for instance an I-beam t5 and adjusted thereon as desired. This beam is formed at its free end with a bearing 46 through which the shifter rod 47 slides. The shifter link 40 is connected with this rod by means of a collar a8 secured thereon and has a pivotal its mounting upon the bolt 49 carried by the collar as shown in Fig. 5. The rod 47 is also provided with any desired construction of belt fingers 50 secured thereto as shown in Fig. l and coiiperating with the tight pulley 51 carried by the shaft 52 mounted in any desired hearing such as shown at 53. This shaft also has the coiiperating loose pulley 54 thereon and the transmitting pulley 55 secured thereto from which power is transmitted by the belt'connection 56 to the driving pulley 12 upon the shaft of the machine.

In the modified form of the invention shown in Fig. 7 the cover 13 is mounted before described and provided with the con necting link 17 extending therefrom. through the aperture 16 in the wall 15. The link is pivotally connected at 60 with a bell-crank disposed.

'or damage to himse lever 61 having a vertically disposed pivot 62 on the bearing bracket 63. he lever is provided with arms (34 and -65 disposed at an angle to each other and ie'latter pivotally connected at GG'with "a connecting rod (57 extending to the shifter lever (38 which is pivotally mounted at 69 upon a bracket 70.

The'connectjng rod 67 is pivoted to this lever at 71. The outer end of the lever is slotted at-72 and there connected with the belt slide 73 which carries the shifting fingers 74: coiiperatingwitli the tight pulley 75 and loose ulley 76 similar to those heretofore descri ed. The slide 73 is mounted upon a bearing 77 having stop blocks 78 to limit the travel of the slide.

In the operation of the invention when the cover is lifted or opened the driving means are shifted through the connections heretofore described so as to cut 0d the power from the machine in order that the operator may be rotected against in'ury f or the goods when aving access to the interior of the machine through the opening at which the cover is When the cover is closed or lowered power is automatically applied for driving the machine. The construction here presen ed provides for a direct and positive transmission of movement from the cover through the rear wall to the shifting connections and the bell-crank lever ivoted to the i adjustment also permits the location of the machine at any esired elevation most convenient to the operator. Y

The invention also provides an improved construction for controlling the power from an over head driving shaft by means of the oppositely disposed bell-crank levers. It will therefore be seen that the invention presents a simple, eiiicient and economically constructed means for securing a positive movement of the belt shifter in either direction of movement of the cover and requires the minimum of power for that purpose.
